Abstract
This utility model relates to oil drilling cementing technology field, particularly relate to a kind of double anti-lost petal universal shaft, including connecting rod and the universal joint that is connected with described connecting rod two ends, described universal joint includes movable joint, bulb, first ball seat, second ball seat, steel ball and pin, described movable joint is with inner chamber, described first ball seat is fixed on the bottom of described inner chamber, described second ball seat is fixed on the end of described connecting rod, described connecting rod two ends bottom thread with described movable joint respectively is connected, carry out spacing by described steel ball between connecting rod and described movable joint, described bulb be respectively arranged at two ends with arc convex, described arc convex coordinates with described first ball seat and the second ball seat respectively；Described bulb end is with annular slot, described annular slot and the described bayonet fittings being arranged on described movable joint.Movable joint has pin positioning lock tieholen compared with routine at lobe tooth, is positioned by pin, and this innovative point is exactly that petal universal shaft can play in place of anti-lost effect one.
Description
Technical field
This utility model relates to oil drilling cementing technology field, particularly relates to a kind of double anti-lost petal universal shaft.
Background technology
At present, oil, natural gas drilling engineering in use helicoid hydraulic motor, the purpose of its universal drive shaft be exactly the eccentric motion of motor rotor is converted to power transmission shaft dead axle motion.The version of the most general universal drive shaft is divided into two kinds, a kind of petal type, a kind of ball shape structure.For anti-lost measure, currently used most be all that housing is anti-lost, bearing is anti-lost and screw thread is anti-lost.And as the universal drive shaft of motion mode conversion supporting body in helicoid hydraulic motor, playing but does not occurs the product of anti-lost effect in Present Domestic market.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and provides a kind of double anti-lost petal universal shaft, has anti-lost function.
This utility model for achieving the above object, by the following technical solutions:
A kind of double anti-lost petal universal shaft, it is characterized in that: include connecting rod and the universal joint being connected with described connecting rod two ends, described universal joint includes movable joint, bulb, first ball seat, second ball seat, steel ball and pin, described movable joint is with inner chamber, described first ball seat is fixed on the bottom of described inner chamber, described second ball seat is fixed on the end of described connecting rod, described connecting rod two ends bottom thread with described movable joint respectively is connected, carry out spacing by described steel ball between connecting rod and described movable joint, described bulb be respectively arranged at two ends with arc convex, described arc convex coordinates with described first ball seat and the second ball seat respectively；Described bulb end is with annular slot, described annular slot and the described bayonet fittings being arranged on described movable joint.
Preferably, cannelure is had at the screw thread of described connecting rod.
The beneficial effects of the utility model are: compared with prior art, bulb be quarter butt two ends be convex shape, the two ends projection of bulb plays the effect of steel ball, i.e. being combined with ball seat concave groove, therefore bulb plays the relative position keeping connecing lobe tooth as the petal universal shaft of ball socket structure and transmits the axial force of motor rotor and the end reaction that offer is necessary simultaneously.But than steel ball and the ball socket structure of conventional petal universal shaft, bulb is bigger with the contact area of ball socket structure and lifting surface area, and therefore effect is better.Movable joint has pin positioning lock tieholen compared with routine at lobe tooth, is positioned by pin, and this innovative point is exactly that petal universal shaft can play in place of anti-lost effect one.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and preferred embodiment describe in detail detailed description of the invention of the present utility model.As shown in Figure 1, a kind of double anti-lost petal universal shaft, including connecting rod 4 and the universal joint that is connected with described connecting rod two ends, described universal joint includes movable joint 1, bulb 2, first ball seat 8, second ball seat 3, steel ball 6 and pin 7, described movable joint is with inner chamber, described first ball seat is fixed on the bottom of described inner chamber, described second ball seat is fixed on the end of described connecting rod, described connecting rod two ends bottom thread with described movable joint respectively is connected, carry out spacing by described steel ball between connecting rod and described movable joint, connecting rod has steel ball access aperture, steel ball is sealed by link block 5 after entering.Described bulb be respectively arranged at two ends with arc convex, described arc convex coordinates with described first ball seat and the second ball seat respectively；Described bulb end is with annular slot, described annular slot and the described bayonet fittings being arranged on described movable joint.Cannelure is had at the screw thread of described connecting rod.
Bulb be quarter butt two ends be convex shape, the two ends projection of bulb plays the effect of steel ball, i.e. being combined with ball seat concave groove, therefore bulb plays the relative position keeping connecing lobe tooth as the petal universal shaft of ball socket structure and transmits the axial force of motor rotor and the end reaction that offer is necessary simultaneously.But than steel ball and the ball socket structure of conventional petal universal shaft, bulb is bigger with the contact area of ball socket structure and lifting surface area, and therefore effect is better.Movable joint has pin positioning lock tieholen compared with routine at lobe tooth, is positioned by pin, and this innovative point is exactly that petal universal shaft can play in place of anti-lost effect one.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
Claims (2)
1. a double anti-lost petal universal shaft, it is characterized in that: include connecting rod and the universal joint being connected with described connecting rod two ends, described universal joint includes movable joint, bulb, first ball seat, second ball seat, steel ball and pin, described movable joint is with inner chamber, described first ball seat is fixed on the bottom of described inner chamber, described second ball seat is fixed on the end of described connecting rod, described connecting rod two ends bottom thread with described movable joint respectively is connected, carry out spacing by described steel ball between connecting rod and described movable joint, described bulb be respectively arranged at two ends with arc convex, described arc convex coordinates with described first ball seat and the second ball seat respectively；Described bulb end is with annular slot, described annular slot and the described bayonet fittings being arranged on described movable joint.
Double anti-lost petal universal shaft the most according to claim 1, it is characterised in that: have cannelure at the screw thread of described connecting rod.
